Patented Oct. 21 1930 UNITED STATES PM I T m n ARTHUR MAUTERER, or nonrmunn, GERMANY COBRUGATED sHEn'r-irrEaten. FILING- Application filed December 23, 1927, Serial No. 242,199, and in Germany December 3, 1926.

In corrugated sheet piling constructions wherein each element forms a complete corrugation in wall surface, the individual elements are liable to bend or bulge about an axis in the cross section of the corrugation corresponding to the direction of the force, when the points of attachment of the individual elements are situated approximately in the axis of the piling and when, in consequence of the relative displacement of the individual elements, the locking members forming the connections do not prevent or hinder bulging. In so far as any friction in the locking connections, for example, offers a hindrance, the bending angle is reduced.

The object of this invention is to prevent undesirable bulging and relative displacement in the locking connections, which object is achieved by alternating the connections, either singly or in groups, whereby any tendency to bulge takes place at right angles to the axis of the piling, since the points of application are disposed in such a manner that the forces neutralize one another.

Two embodiments of the invention are illustrated in the accompanying drawing to which reference will now be made and wherein Fig. 1 represents a plan view of one of these forms in which the corrugated pile elements are directly connected together; and

Fig. 2 is a similar view of another form in which the corrugated pile elements are connected together by intermediate members.

As shown in Fig. 1, adjacent corrugated pile elements, denoted a and b, are interlocked at 0 in such manner that the wider or intermediate portions cl and e of the elements do not lie parallel, as in the case of the usual connection, but diverge. words, the pile elements constituting the wall are alternately inverted. It will be seen that all the pile elements are of the same section and that each is formed with a malelocking member at one end and with a female looking member at the other end.

In Fig. 2 the same result is obtained as in Fig. 1 by interposing a member f in the form of a half corrugation between the adjacent In other corrugated pile elements which are reversed as before. i

Said intermediate members may be of any convenient form according to circumstances; they may, for example, be hollow pile members which constitute an'additional stiffening.

\Vhile the invention is illustrated in application to pile elements each in the form of a complete corrugation, it will be manifest that 3 pile elements each in the form of a half corrugation may be used and united in pairs, by pressing or the like, so as practically to constitute completely corrugated units.

Having now particularly described and ascertained the nature of my said invention and in What manner the same is to be performed, I declare that what I claim is 1. A sheet piling wall comprising 8 shaped metal sections alternated inversely with U shaped sections so as to give regular and continuous wave or corrugational form to the wall, said sections belng connectedend to end by interlocking marginal portions.

2. A sheet piling wall comprising S shaped sections of S or full wave form (in cross-section) alternated in inverse relation with similar metal sections of U or only half-Wave form (in cross-section) with resultant effect of regular and continuous corrugation of the Wall surfaces; the individual sections being connected end to end by interlocking marginal portions providing male and female joints.

4. Sheet metal piling of regular and continuous corrugated form comprising pile-sections of S or full-wave shape (in cross-section) and pile-sections of U oronly half- Wave shape (in cross-section) alternated therewith inversely at regular intervals; the

said sections being connected end to end by interlocking marginal portions.

5. Sheet metal piling of regular and continuous corrugated form comprising pile-sections of S or full-Wave shape (in cross-section) and pile-sections of U or only half-wave shape (in cross-section), the latter being employed singly in alternately inverse position, at lntervals between groups of the former, and said sections being connected end to end along the axis of the Wall by marginal portions thereof interlocking each With others.

6. A sheet piling Wall comprising a plurality of corrugated metal sections of S or full-Wave shape and a plurality of metal sections of U or only half-Wave shape connected together end to end With single of the U shaped sections alternated inversely at intervals with the former; said sections being connected by interlocking marginal portions providing male and female joints.

In testimony whereof I have aflixed my signature.

ARTHUR MAUTERER.
